ある。Description: TECHNICAL FIELD The present invention relates to a telephone switching network control system, and particularly to a telephone when an exchange having a relay switching function in a star-shaped telephone switching network fails. The present invention relates to a telephone switching network control system improved to enable quick restoration of a switching network.
従来、この種の電話交換網制御方式は、障害となった交
換機の代りに可搬型交換機を使用することにより電話交
換網を復旧させる方式となっていた。Conventionally, this type of telephone switching network control system has been a system for recovering the telephone switching network by using a portable switching system instead of the failed switching system.

換機の障害発生から電話交換網を復旧させるまでには、
可搬型交換機の立上げ，中継線の接続替等の作業が必要
なため、長時間を要するという欠点がある。Since the conventional telephone switching network control method described above is designed to restore the telephone switching network by using a portable switching device, it is necessary to restore the telephone switching network from the failure occurrence of the switching device.
There is a drawback that it takes a long time because the work of starting up the portable exchange and changing the connection of the relay line is required.

る。The telephone switching network control system of the present invention is a control system for restoring a telephone switching network when a switching system having a relay switching function in a telephone switching network composed of a star-shaped network becomes a failure. Means for connecting the trunk line between the upper-layer exchanges and the relay line between the faulty exchange and the lower-layer exchange,
It is characterized in that it is provided with remote control means for changing the route information for each associated exchange and restores the telephone exchange network in a state where the faulty exchange is removed.
次に、本発明について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.

態で電話交換網を復旧させる。When the exchange 4 is in failure, the line switching control unit 1 disconnects the relay lines 7, 8, 9 and 10 and the exchange 4 in the line switching unit 2 and the relay lines 7, 9 and 8 and 10 are released. And the relay lines 7, 8, 9 and 10 by the route information change signals transmitted from the line switching control unit 1 to the exchanges 3, 5 and 6 via the remote control units 11, 12 and 13 respectively. The telephone exchange network is restored with the faulty exchange removed by changing the route information.

状態で電話交換網の迅速な復旧ができる効果がある。As described above, according to the present invention, when the telephone switching network is brought into the system down state due to the failure of the exchange, the relay line between the faulty exchange and the upper station exchange and the relay line between the faulty exchange and the lower station are connected. The effect is that the telephone switching network can be quickly restored without the faulty exchange.
